The physical-mechanical properties was studied for the composite material (the highly concentrated suspension based on distilled water, ultra fine brown coal, nano particles of the globular carbon T-900). It was found that carbon nano particles at low concentrations (0.04, 0.08 2 wt.%) can be dispersing agents. Under certain cavitation modes the surface segregation of oxygen impurities was detected in the nano carbon particles. The combustion kinetics of dispersed phase powder of suspension with the addition of 2 wt.% nano carbon differs from the original coal combustion.
